Introduction to Zbrush Digital Tutors
Basic Polypainting
– Polypainting is colouring a mesh using the polygons rather than a UV-based texture map. Polypainted models can be used to create texture maps, but for high-resolution maps a high-polygon model is required.
– Polypainting uses the same brushes as sculpting, but ZAdd and ZSub should be switched off and the RGB channel switched on.
– If you try to choose a colour now the whole mesh will change. To start polypainting properly, select Colour > FillObject. The mesh now has a colour applied and new colours can be selected for polypainting.
– Colour can be combined with strokes and alphas to get different paint effects.
– to pick a colour from the model, LMB + Drag from the colour palette onto the model. The cursor will change to the Pick symbol.
– Use DragRect stroke with alphas to draw coloured instances of that alpha.
– Rgb Intensity slider determines the strength of the polypainting colour. A higher intensity builds up colour more quickly.
– Sculpting and polypainting can be done at the same time, eg for sculpting boils and pimples.
